JAK Inhibitors Show Promise For Treatment of Severe Alopecia Areata

MedicalResearch.com Interview with:
Brett King, MD, PhD, FAAD
Associate Professor of Dermatology
Yale School of Medicine

MedicalResearch.com:  What is the background for this study? 

Response: Alopecia areata is an autoimmune disorder marked by disfiguring, non-scarring hair loss, and there are no therapies approved by the U.S. Food and Drug Administration for treatment of the disease. JAK inhibitors are showing promise for treatment of severe alopecia areata. In this work, the pooled results of two phase 3 clinical trials of the JAK inhibitor baricitinib were reported out to 52 weeks.

MedicalResearch.com:  What are the main findings?

Response: In adults with severe alopecia areata (≥50% scalp hair loss) – average scalp hair loss was approximately 80%, and about half of patients had no scalp hair – treatment with baricitinib demonstrated scalp, eyebrow, and eyelash hair regrowth. Almost 40% and 25% of patients treated with baricitinib 4 mg and 2 mg, respectively, achieved ≤20% scalp hair loss during 52 weeks of treatment. 

MedicalResearch.com: What should readers take away from your report?

Response: The JAK inhibitor baricitinib is effective for treatment of alopecia areata. Hopefully, we will soon have treatment to reverse this often awful disease! 

MedicalResearch.com: What recommendations do you have for future research as a result of this work?

Response: We want to see results of longer treatment with baricitinib to see if efficacy continues to rise past 1 year. 

MedicalResearch.com: Is there anything else you would like to add?

Response: Dr. Brett King has served on advisory boards and/or is a consultant and/or is a clinical trial investigator for Abbvie, AltruBio Inc, Almirall, AnaptysBio, Arena Pharmaceuticals, Bioniz Therapeutics, Bristol-Meyers Squibb, Concert Pharmaceuticals Inc, Horizon Therapeutics, Eli Lilly and Company, Incyte Corp, LEO Pharma, Otsuka/Visterra Inc, Pfizer Inc, Regeneron, Sanofi Genzyme, TWi Biotechnology Inc, and Viela Bio.
